Spectacularly preserved viscous flow on the NE rim of Byrgius A (19 km diameter) crater. This flow has a form similar to lava flows on the Earth - however it formed as a result of an asteroid or comet slamming into the Moon at hyper-velocity (>16 km/second). So much energy was released in the impact that solid rock was melted and thrown out of the crater where it flowed down the crater flanks (M102573276L, image width 810 m) [NASA/GSFC/Arizona State University].
